“Productivity is a measure of output from a production process, per unit of input.”
For this experiment, we will be comparing the productivity of two different types of flour used in baking: Self-raising and Plain. The quantities are equal for both types of flour.
Begin by measuring out 4oz of sugar and 4oz of butter.
Cream and add an egg. Then mix.
Add half a tsp of Vanilla Extract or essence.
Measure 4oz of flour.
And mix until you have a thick dough type mixture.
Add enough milk to loosen the mixture. You want it to be of moosey consistency.
Pour the mixture into a well greased baking tin. Pop in the oven at 180c for around 30 mins.
The results are out. The cake with plain flour is on the left and the self-raising cake on the right in the tin. This was because an air-bubble was caught and exploded the cake in the oven. However, it also indicates that the cake using self-raising flour has explosive productivity, whereas the cake baked with plain flour does not.
Self-raising flour is more productive than plain flour.
